When your users want to get from one location to another, don’t push them out of your application into a generic map application. Instead, keep them engaged with your application 100% of the time with in-app turn-by-turn navigation.

The Mapbox Navigation SDK is a precise and flexible platform which contains logic needed to get timed navigation instructions and enables your users to explore the world's streets. We are designing new maps specifically for navigation that highlight traffic conditions and helpful landmarks. The calculations use the user's current location and compare it to the current route that the user's traversing to provide critical information at any given moment.

This library aids in adding four tabs in Bottom Navigation Bar, as easily and fast as possible. Th result looks like as it is commonly found in most of the apps, like Quora and others.

Point to note: This library is significantly different from what Google has provided for Android Developers. The official Bottom Navigation Bar from Google doesn't show text when it has 4 tabs. But this library shows icon and text with four bottom bars.
